DELAHANTY AND ONE-HALF T0 STEWART BROWN, OF CHICAGO, ILLINOIS,

REFLECTOR-JEWEL MOUNTING.

Application filed August 15, 1925. Serial No. 50,474.

My invention relates to in'lprovements in mounting for reflector jewels, such as are used at the rear of bicycles, automobiles, and other vehicles for showing a red warning light to vehicle: approaching from the rear when the lights of such vehicles fall on the jewel, and it consists in the combinations, constructions, and arrangements herein described and claimed.

The use of reflector jewels which consist of discs of red glass having prismatic faces and backed by a reflecting medium, as warning signals to approaching vehicles having headlights, is ordinary. Such reflector ewels generally have a .mounting including a threaded stud which may be passed through an opening in some portion of the vehicle, such as the mud-guard of a bicycle or the fender of an automobile Where it is held by a nut. This means of mounting the reflector not only is expensive, but it necessitates the drilling of an opening through the mudguard or fender when the reflector jewel is attached.

An object of my invention is to provide a reflector jewel mounting of the type mentioned in which the necessity for drilling a hole in the fender or mud-guard is obviated.

A further object of my invention is to provide a mounting comprising a clamping device which is secured to the jewel reflector casing in a novel manner, and which is relatively cheap to manufacture.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a face view of the reflector jewel, v

Figure 2 is a section through the mount- I ing along the line 2-2 of Figure 1, showingthe parts in their position befote the casing is crimped over the edge of the jewel, and

Figure 3 is a similar section, showing the parts in their normal position when attached to a support, such as a fender or mud-guard.

In carrying out my invention I make use of a jewelA, such as'that mentioned. This is a disc of red glass, preferably having triangular faces and being backed by some reflecting material to form a mirror. I

The casing B is formed preferably of metal, such as brass, and consists of a cylindrical member closed at the rear end 6, but being provided with a rectangular opening a.

The clamp consists of a U-shaped member C of metal, one arm of the clamp being threaded and being provided with a set screw D. The opposite arm is arranged to pass through the opening 0 and to fit against the back 6 of the casing. Between the arm of the clamp which is within the casing and the jewel A is a dish-shaped disc E., This disc, as will be observed, is convex on that side adjacent. to the arm of the clamp C and is arranged to bear on the arm at its central portion. The edge of the disc E is within the edge of the-casing B and is contiguous with the rear edge of the reflector jewel so as to form a backing for it. The arrangement of the parts before the final crimping operation is shown in Figure 2. When now the edge 6, is crimped over the edge of the jewel reflector, the parts will be held firmly in position, since-it is obvious that there can be no movement of the clamp which must necessarily swing inwardly in order to pass out of the hole :0. The dishshaped disc E besides forming a backing for the jewel and a means of retaining the clamp against the back of the casing, has

a cushion eflect from the dished form. The" device is attached to a support, such as a 'U-shaped clamping member having one arm arranged to enter the opening, an intermediate dish-shaped disc between the jewel and said arm for holding the jewel and the arm against portions of the casing, and a set screw carried by the other arm movable toward and away from the rear of the casing.

2. The combination with a reflector jewel,

of a casing therefor having an opening, a U-shaped clamping member having one arm arranged to enter the openin and to lie against the back of the casing, a dishshaped disc disposed between said arm and the jewel, the convex side of the disc being arranged to bear on the arm, and the edge of the casing being crimped' to hold the jewel against the edge of the dish-shaped disc on the convex side thereof, the other 10 arm of the clamping member being provided with a set screw movable toward and away from the rear of the casing.
